Abstract

TanDEM-X is a high-resolution interferometric mission with the main goal of providing a global and unprecedentedly
accurate digital elevation model (DEM) of the Earth surface by means of single-pass X-band SAR interferometry. Despite
its usual quasi-monostatic configuration, TanDEM-X is the first genuinely bistatic SAR system in space. During its
monostatic commissioning phase, the system has been mainly operated in pursuit monostatic mode. However, some
pioneering bistatic SAR experiments with both satellites commanded in non-nominal modes have been conducted with
themain purpose of testing the performance of both space and ground segments in very demanding scenarios. In particular,
this paper reports about the first bistatic acquisition and the first single-pass interferometric (mono/bistatic) acquisition
with TanDEM-X, addressing their innovative aspects and focussing on the analysis of the experimental results. Even
in the absence of essential synchronisation and calibration information, bistatic images and interferograms with similar
quality to pursuit monostatic have been obtained.
